Abstract

The synthesis of some new coordination compounds for cobalt (II), nickel(II)and copper(II)with Schiff bases derived from(2-aminobenzothiazole,6-nitro-2-aminobenzothiazole,4,6-dibromo-2-aminobenzothiazole) and 4-N-dimethylbezaldehyde to give ligands (La,Lan and Ladb) were prepared and then reacted with metal salts in ethanol as a solvent in 1:2 ratio (metal : ligand). The complexes which have the general formula [ML2Cl2] Where M=Co (II) , Ni (II) and Cu (II),( L=La,Lan,or Ladb) all ligands and it's metal complexes were characterized using metal analysis by Atomic absorption, Infrared spectra ,Electronic spectra, Molar conductance and Magnetic moment measurements ; These measurements indicated that the ligands coordinate with metal (II) ion in a bidentate manner through the nitrogen atoms in ligands, Octahedral structures were suggested for metal complexes.
